The data set bundle comprises geochemical, XRF core scanning and pollen data from composite sediment core BIS-2000, which was compiled from two parallel sediment cores (BIS-1 and BIS-3) obtained near Bispingen, northern Germany (53.071528°N, 9.989861°E, 82.0 m). BIS-2000 comprises Last Interglacial (Eemian) to early Last Glacial (Weichselian) palaeolake deposits, which cover the section between 15.55 and 30.68 m composite depth.
The data set Bispingen BIS-2000 XRF contains results of XRF core scanning. Analyses were carried out at the GFZ German Research Centre for Geosciences in Potsdam, Germany, on the section between 15.08 and 31.20 m composite depth. Split sediment core segments were scanned with an ITRAX XRF core scanner and measured intensities of silicon, calcium and titanium were used to calculate the log-ratios log(Si/Ti) and log(Ca/Ti).
In order to reconstruct the presence of Megafauna in relation to vegetation cover in Central Europe, a total of 250 pollen samples and 203 samples for spores of the coprophilous fungi Sporormiella and Sordaria were analyzed. The results are accompanied by measurements of δ7Li and n-alkanes. Samples derive from composite drill cores from Holzmaar and Auel infilled maar and cover the last 60,000 years. This work is part of the ELSA project.
n-alkane peak areas from GC-FID measurements. Compound specific hydrogen and carbon isotope measurements made using GC-IRMS. Samples taken from Auel Maar, Holzmaar, and Schalkenmehrener maar lake sediment cores spanning 60,000 years. Age model information and additional proxy data from the ELSA-20 stack are found in Sirocko et al., 2021 (Nature Geoscience) and Sirocko et al., 2022 (Scientific Reports).
